Overall requirements for a non-bootable data volume
For a system to be able to address the maximum capacity of a device that has a storage capacity of more than 2 TB, the following prerequisites apply:
The disk must be initialized by using GPT.
The Windows version must be one of the following (32-bit or 64-bit, unless otherwise noted, but including all SKU editions):
Windows Server 2008 R2 (only 64 bit version available)
Windows Server 2008
Windows 7
Windows Vista
The latest storage drivers from your storage controller manufacturer must be installed. For example, if your system uses an Intel storage controller that is set to “RAID” mode, make sure that you have the latest applicable drivers from the Intel support site.
Overall, you should contact your system vendor to determine whether the system supports device sizes of more than 2 TB.
Overall requirements for a bootable system volume
Assume that you want to meet the following conditions:
Have a storage device on which you can install Windows.
Make the storage device bootable.
Enable the operating system to address a maximum storage capacity for that device of greater than 2 TB.
To meet these conditions, the following prerequisites apply:
The disk must be initialized by using GPT.
The system firmware must use UEFI.
The Windows version must be one of the following (64-bit only, but including all SKU editions):
Windows Server 2008 R2
Windows Server 2008
Windows 7
Windows Vista
The latest storage drivers from your storage controller manufacturer must be installed. For example, if your system uses an Intel storage controller set to “RAID” mode, make sure that you have the latest applicable drivers from the Intel support site.
Note Windows does not support starting GPT-initialized volumes by using UEFI systems on 32-bit versions of Windows. Also, legacy BIOS systems do not support starting GPT-partitioned volumes. Consult your system vendor to determine whether the system supports both UEFI and the startup of devices that have storage capacities of greater than 2 TB.
